36" long (3 ft) hose Oxygen transfill device to fill you own oxygen H tanks (CGA-540) from your Homefill unit. One end of the device plugs into the port where you would normally plug in your Homefill oxygen tank and the other end attaches to an H tank (or any CGA-540 tank) via the 36" hose; giving you the ability to fill a much larger oxygen tank than what is standard on the Homefill device.

Includes CGA-540 E tank yoke so unit can fill both CGA-540 tanks and CGA-870 E tanks.
